All left wing economic ideology is based upon variations of the broken window fallacy of wealth creation. If you think labor creates value, then breaking the glass requires labor, and wealth appears to have been created. The realist focuses upon the capital goods, and finds that there is no net gain, and that capital has been redirected for no good reason.

For the Low Informationals: Keynesian Stimulus economics consists of taking money from the private sector; subtracting the cost of taking money from the private sector; further subtracting the cost of the attending graft and corruption that always goes hand in hand with taking money from the private sector; then returning some of the money that is left back to cronies and supporters in the private sector.
